<Tab title="LangChain">

Integrating with Langchain is super easy! Just change the base_url

```ini
export OPENAI_API_BASE="https://oai.hconeai.com/v1"
python3 you_lang_chain_program.py
```

</Tab>

<Tab title="gpt_index">

Since GPT Index uses lang chain under the hood, you can use the same technique
to integrate as well

```ini
export OPENAI_API_BASE="https://oai.hconeai.com/v1"
python3 you_lang_chain_program.py
```

import "github.com/fabiustech/openai"

func main() {
	var client = openai.NewClient("your token")
	client.SetBaseURL("https://oai.hconeai.com/v1")
